Renal denervation reduces atrial remodeling in hypertensive rats with metabolic syndrome.

Atrial fibrillation (AF) is highly prevalent in hypertensive patients with metabolic syndrome and is related to inflammation and activation of the sympathoadrenergic system. The multi-ligand Receptor-for-Advanced-Glycation-End-products (RAGE) activates inflammation-associated tissue remodeling and is regulated by the sympathetic nervous system. Its counterpart, soluble RAGE (sRAGE), serves as anti-inflammatory decoy receptor with protective properties.

Renal Denervation Prevents Atrial Arrhythmogenic Substrate Development in CKD.

Background: In patients with chronic kidney disease (CKD), atrial fibrillation (AF) is highly prevalent and represents a major risk factor for stroke and death. CKD is associated with atrial proarrhythmic remodeling and activation of the sympathetic nervous system. Whether reduction of the sympathetic nerve activity by renal denervation (RDN) inhibits AF vulnerability in CKD is unknown.

The Multi-Purpose Airborne Sensor Carrier MASC-3 for Wind and Turbulence Measurements in the Atmospheric Boundary Layer.

For atmospheric boundary-layer (ABL) studies, unmanned aircraft systems (UAS) can provide new information in addition to traditional in-situ measurements, or by ground- or satellite-based remote sensing techniques. The ability of fixed-wing UAS to transect the ABL in short time supplement ground-based measurements and the ability to extent the data horizontally and vertically allows manifold investigations. Thus, the measurements can provide many new possibilities for investigating the ABL.

Blood Pressure and Cognitive Performance After a Single Administration of a Camphor-Crataegus Combination in Adolescents with Low Blood Pressure.

Low blood pressure is rather widespread among adolescents and frequently accompanied by complaints. Two single-center, double-blinded, randomized, and placebo-controlled trials were performed with adolescent participants in the age range of 14 - 17 y having a systolic blood pressure below 118 mmHg (boys) or 110 mmHg (girls). They received a single dose of 20 drops of a fixed combination of natural D-camphor and an ethanolic extract from fresh berries (CCC) or of an ethanolic placebo.

In ovo expression of microRNA in ventral chick midbrain.

Non-coding RNAs are additional players in regulating gene expression. Targeted in ovo electroporation of specific areas provides a unique tool for spatial and temporal control of ectopic microRNA expression. However, ventral brain structures like ventral midbrain are rather difficult to reach for any manipulations.
